Kingston upon Thames has the plots that suit good extensions, from the side returns and rear closet wings of its Victorian and Edwardian terraces to the generous gardens of larger houses near Bushy Park. GS Renovation designs and builds single and double storey extensions across KT1 to KT6, drawing on more than 30 years in the borough.
Side-return extensions across Kingston terraces
The side return is the strip of ground beside the rear closet wing on a Kingston terrace, usually wasted on a narrow passage. Filling it in widens a cramped galley kitchen into a bright kitchen-diner running the full width of the house. We dig new foundations to suit the ground, tie into the existing wall, install steel to carry the opened structure and add a glazed roof or rooflights to pull daylight deep into the plan.
Whether your extension is permitted development or needs a full planning application depends on the property. Many single storey rear and side-return builds in KT1, KT2 and KT3 fall within permitted development, but homes in a conservation area, or those already extended, usually need permission from Kingston Council. We advise on which route applies, prepare the drawings, handle the party wall notices where a boundary wall is shared and build the whole thing to building regulations.
Double storey and wrap-around Kingston extensions
On the larger period houses towards Surbiton and New Malden, a wrap-around extension combines the side return with a rear projection to transform the whole ground floor, while a double storey build adds a bedroom or en-suite above. These schemes almost always need planning permission from Kingston Council and careful structural design, because new steel and foundations must work with existing walls that were never built to carry the extra load. We manage the engineering from the start.
One team takes the project from foundations to final fit-out, so groundworks, steel, roofing, plastering, kitchen and decoration all follow one programme. We keep the disruption contained while you live in the house, protect the garden and access, and coordinate building control inspections at each key stage. The result ties into the original brickwork and rooflines of your Kingston home rather than looking bolted on, and it is signed off with the paperwork you will need later.
